Description

Technical Field

[0001] The invention relates to the technical field of automobile motor accessories, and in particular to an integrated electrode brush holder ring and a sheath structure. Background Art

[0002] Existing motors all use a brush holder ring structure including a brush holder ring component, a spring component and a baffle, wherein the brush holder ring component is annular, and the brush holder ring component, the spring component and the baffle are separate structures. The baffle is used to fix the ball bearing in cooperation with the bearing chamber of the reduction housing; the brush holder ring is used to ensure the matching distance between the brush and the commutator and to assemble other components, and the spring component is used to collect the signal of the motor "stopping" (stopping work). This type of brush holder ring structure has the following disadvantages: The brush holder ring structure separates the brush holder ring component, spring component and baffle into a separate structure. Therefore, the brush holder ring structure is relatively complex and the assembly is cumbersome. At the same time, the ring-shaped brush holder ring component is not easy to operate when assembling the armature component. In order to solve the above technical problems, the Chinese patent document (CN107994718A) discloses a new brush holder ring component structure for the rear wiper motor. The lower part of the brush holder ring body adopts a semi-circular ring opening structure, which corresponds to the baffle. The brush holder ring part and the baffle and spring component in the rear wiper motor are designed as a whole. At the same time, the circuit connection between the brush holder ring component and the plug sheath adopts the contact spring piece and the plug piece to cooperate.

[0003] Although the above technical solution forms a brush holder ring component by designing the baffle plate and the spring part as a whole, and the brush holder ring component and the plug sheath are plugged and connected through the contact spring plate and the plug plate, the technical problem of complicated assembly caused by the split structure can be reduced. However, in actual use, there are the following technical problems: 1) Since the plug piece of the plug sheath needs to be plugged into the contact spring piece and connected to the brush holder ring component, in the production process of the brush holder ring component of the above technical solution, the contact spring piece needs to be customized, resulting in an increase in the cost of producing parts; at the same time, the contact spring piece needs to be installed on the brush holder ring component, resulting in an increase in the installation labor cost; 2) Since the plug piece of the plug sheath needs to be plugged into the contact spring piece and connected with the brush holder ring component, the plug sheath and the brush holder ring component need to be produced separately during the production process, resulting in increased production time and cost. At the same time, after the plug sheath and the brush holder ring component are produced separately, the plug piece of the plug sheath needs to be manually plugged into the contact spring piece of the brush holder ring component, resulting in increased labor costs for production; 3) In actual use, since the plug piece of the plug cover needs to be inserted into the contact spring piece and connected with the brush holder ring component, the connection between the plug cover and the brush holder ring component is not stable, and the reliability of the connection between the two is poor, thereby affecting the performance of the motor. Summary of the invention

[0004] The present invention intends to provide an integrated electrode brush holder ring and sheath structure, which can solve the above technical problems of cost and reliability.

[0005] In order to achieve the above object, the present invention adopts the following technical scheme: 1) An integrated electrode brush holder ring and sheath structure, comprising a brush holder ring shell and a sheath shell, wherein the brush holder ring shell and the sheath shell are integrally formed, wherein the brush holder ring shell has a first brush, a second brush and a first spring sheet, and wherein the sheath shell has a first plug sheet, a second plug sheet and a third plug sheet extending along the length direction of the brush holder ring shell and bent downward; The end of the first plug close to the brush holder ring shell extends toward the first spring sheet and is welded with the first spring sheet to form a first circuit line. The second plug extends toward the inside of the brush holder ring shell and cooperates with the second brush to form a second circuit line. The third plug extends toward the inside of the brush holder ring shell and cooperates with the first brush to form a third circuit line. The internal circuit of the brush holder ring is connected with the internal circuit of the sheath through the first circuit line, the second circuit line and the third circuit line to form an integrated structure.

[0006] The present invention is cleverly designed. By injection molding the brush holder ring shell and the sleeve shell into an integral structure, it is no longer necessary to separately produce the brush holder ring shell and the sleeve shell when producing the brush holder ring shell and the sleeve shell. Instead, the brush holder ring shell and the sleeve shell are directly injection molded into an integral structure, thereby reducing production time costs and improving production efficiency.

[0007] In addition, the present invention eliminates the contact spring sheet in the prior art, and designs the plug sheet in the plug sleeve in the prior art to form a first plug sheet, a second plug sheet and a third plug sheet extending toward the brush holder ring housing. Therefore, compared with the prior art, this design no longer requires the separate production of the contact spring sheet and the plug sheet, thereby reducing the cost increase of producing parts and the labor cost of installing parts.

[0008] At the same time, the first plug, the second plug and the third plug designed in the present invention each extend as a whole along the length direction of the brush holder ring shell and bend downward to form an inverted L-shaped structure, thereby connecting the first plug in the sheath shell to the first circuit line in the brush holder ring shell, the second plug in the sheath shell to the second circuit line in the brush holder ring shell, and the third plug in the sheath shell to the third circuit line in the brush holder ring shell. Therefore, the internal circuit of the brush holder ring is connected to the internal circuit of the sheath through the first circuit line, the second circuit line and the third circuit line to form an integrated structure, thereby ensuring the stability and reliability of the connection between the internal circuit of the brush holder ring and the internal circuit of the sheath, thereby improving the performance of the motor.

[0012] The second electrical circuit of the present invention includes a protector, a capacitor and a second brush. When the second electrical circuit between the internal circuit of the brush ring frame and the internal circuit of the sheath is formed into an integrated structure, a point contact transmission method is adopted, and the second socket opened at the end of the second spring sheet is used to synchronously clamp the upper contact piece of the protector, the second wire of the capacitor, and the plug connector of the second plug sheet, so that the upper contact piece, the second wire and the plug connector are attached to each other and welded together to form an integrated structure, thereby ensuring the stability and reliability of the second circuit line between the internal circuit of the brush ring frame and the internal circuit of the sheath, and at the same time replacing the structure of the contact spring sheet in the prior art, saving material costs.

[0014] The third circuit line of the present invention includes a capacitor, an inductor and a first brush. When the third circuit line between the internal current of the brush ring frame and the internal circuit of the sheath is formed into an integrated structure, a clamping welding transmission method is adopted, and the double contact wires are clamped and welded using the clamping holes on the clamping joint. At the same time, the double contact wires are designed to be parallel to each other and are synchronously clamped into the clamping joint and welded, so that the double contact wires form a circuit connection in the clamping joint, so that the capacitor and inductor respectively connected to the double contact wires form a circuit line with the third plug-in sheet here, thereby ensuring the stability and reliability of the third circuit line between the internal circuit of the brush ring frame and the internal circuit of the sheath, and at the same time replacing the structure of the contact spring sheet in the prior art, saving material costs.
